Roll Parallelism


RollCheck_Green The practical front-line solution.



RollCheck_Green is an ideal tool for fitters and maintenance people:
  • It’s very easy to use and requires no Surveying or Instrumentation background.
  • Ideal for roll replacement or repair situations
  • Low price and ready for immediate use
  • Shorter downtime and precise alignment.
  • Compact design, fits into the smallest spacesNo Training required




    • What you see is what you get:
    The RollCheck® laser alignment system for parallel roll alignment is lightweight, compact and durable. The system can be magnetically attached to just about any size roll or attached with the supplied straps.
    We use our proven reflected laser beam technology for maximum angular resolution, thus providing you with the most reliable and accurate visual reading.
    The RollCheck® can measure spans up to 10 ft. (3 m) from roll to roll of any size, large or small. A laser line is projected from the RollCheck® transmitter to the reflector mounted on the roll to be checked or aligned.
    The laser line projected to the reference line on the reflector indicates immediately if the roll is aligned vertically to the stationary roll. The laser line is then automatically reflected back to the transmitter’s reference line indicating if the rolls are parallel to one another. This system is very easy to use; a single person can perform the alignment task in minutes with no training! The RollCheck® comes in its own durable carrying case.

    Measurement of rolls

    Measuring Parallelism


    Your task is to measure and align rolls or machine components which are not adjacent to one another.

    Be it paper machine cylinder rolls or printer elements or just 2 transport guides - the process remains very similar. We can create a reference line perpendicular to our reference roll,outside the machine using a laser receiver at each end. The T310 Laser transmitter and the R310 receivers are able to communicate with each other using Infra-red light; This makes lining up for the following measurements much easier. Now the right angle static beam can be used to measure the position of the roll to be measured with respect to the reference.

    Measurement resolution of 0,01mm.

    In other words, when the reference line sensors are 20m apart, the system measurement error is reduced to within 0,5µm per metre of roll length.

    Required Hardware


    Equipment package:

    For rapid and precise measurement of parallelism you require one T330 Laser and at least two R310s. The R525 receiver together with the UMPC package IT 200320 are also necessary. We also need one or two tripods with the appropriate height range.

    We offer training and retail services for this equipment.
